The two-lane route heads eastward from the junction, winding to the north and south across open, rolling terrain with several cultivated fields.

After 1 mile (1.6 km), the highway meets County Route 19 (CR 19, named East Road) and turns to the northeast toward the village of Castorland.

The route passes through the center of the village, serving four lightly developed residential blocks before crossing the Mohawk, Adirondack and Northern Railroad at the northeastern edge of the community.
